This bag has been great in surviving a six-week term at school. It is nice and strong, so can carry lots of A4 books, however doesn't fit any folders inside. The strap is nice and wide, so it is also comfortable to carry, and doesn't hurt your shoulder. The corners have got a bit scuffed during this time, but overall, they have stayed in good shape. Also, the bag went a bit dis-coloured when I had it out in the rain. The original colour has come back a bit, now, but it is still a slightly gray-ish colour. Overall, a reccommmended bag to purchase!
